The Megger TM1600 circuit breaker analyzer measures a circuit breaker’s timing cycle. The timing channels record closings and openings of main contacts, resistor contacts and auxiliary contacts. Since the timing channels are not interconnected, you can take measurements of resistor contacts and series-connected breaker chambers without having to disconnect them.
The Megger TTR100 is an automatic handheld, battery operated transformer turns ratio test set used to measure the turns ratio, excitation current, phase displacement, dc resistance and polarity of windings in single- and three-phase distribution transformers (tested phase by phase), potential & current transformers, and tapped transformers.
The Megger TTR310 turns ratio test set is designed to measure the turns ratio of power, instrument, and distribution transformers in a substation or manufacturing environment.
